  • Friction clutch driven plate
    Patent number: 4301907
    Abstract: This invention relates to friction clutch driven plates and in particular to motor vehicle clutch driven plates which require both an idling vibration damper and a load vibration damper. The driven plate comprises two concentric hubs, on one of which is mounted a friction facing carrier capable of restrained angular movement about the hubs. The hubs each have spring seatings which are arranged in a common radial plane and springs act between the seatings to oppose relative rotational movement between the hubs.
